Our 2006 Sienna XLE with 192,000 miles will occasionally have the Vehicle Stability Control (VSC) sensor go on when driving. Typically this occurs when going around a modest curve or slight dip in the road at posted speeds. The sensor causes an audible alarm and in some cases the vehicle will start to brake and the steering wheel will “lock” for a very short time (about 2 to 3 seconds). It is very un-nerving when this sensor comes on. The Toyota dealership believes this issue is due to the rack and pinion needing replacement which would cost more than the car is worth. I read somewhere that parking the car on a flat surface with the wheels straight and then disconnecting the battery can “reset” the vehicle sensor. I tried this and it seemed to work for maybe 9 months before the VSC came on again.
Does anyone else have experience with this issue and possible economical solutions.
